' c .'LIeuiDK-FEEDING DEVICE.`

, Application filed November 28, 1927. Serial No. 236,141.

Myinvention relates to devices for feeding l. liquid to oil'burners or other devices requiring a liquid to be ted thereto under constant pressure. It has for-itsprincipal object a der vice'which'maintains a supply of liquidl at a constant level. F urther principal objects are to combine a strainer with a device for maintainingthe head; to make it possible .toremove the "strainer for cleaning Without losing any of the liquid,'t'o make a device which will not corrode and to provide a valvethat will not sticker clog.

` The invention consists principally in theV liquid feeding device andin the-1 parts and f combinations and arrangements of n l y b Y hereinafter described and claimed.

Fig. 1 is a diagrammatic'elevation of a liquid feeding device embodying my invention;

Fig. 2'is a vertical sectional view on the line Y 2 2 ofiug. 4., Y

Fig. 3 is a vertical sectional View on the line 3-.3 in Fig. 2; and y Fig. 4 isa top plan view. Y An upper housing member 1 is provided' with 'an inlet pipe 2 that is connected to a' tank 3 or. the like affording a supply of liquid such as fuel for an oil-burner.l A-shut-off` valve 4 is provided ini the pipe line 2. Supported in said upper housing'l'is a strainer 5. "The strainer 5 shown in the drawings has a solid bottom 6 to which are secured;lengitudinal stiii'ening members 7 and at the top is a ring 8 that rests on an housing 1. u

"A cap 1() is provided for thetop of's'aid housing 1 said caphavi'ng an annular rib 11 resting on a' gasket 12 seatedv on an annular ledge 131m said housing 1. vSaid caplO is heldin positionV by means of a' clamp'bar'lt annular lledge -9 in the Y having aconvexly curved surfacel that en? gages the top of the cap 10. Said clamp bar, 14 isheld in place by bolts 1G aiid'nuts 17.'

Secured to the underside of the cap 10, as by a screw 18, is a spring 19, preferably made of" partsv -k member 24.

In the accompanying drawing wherein like .referenceiiumerals refer -`'to like parts wher'-v ever they occur, f strainer apipe 23 that leads to a burner or other'` de vice. Mounted in said lower housing 21 lis FICE.,

a float 24 to which are-secured arms 25that k are pivotally secured to depending members 26 on the bottoni ofv said upper housing 1. Threaded into a hole in the bottom of said upperhousing 1 is a tubular member 27. that has an annular rib 28 that rests on a gasket 2K9 or packingrinfr in the bottom of said upper housing 1. aid tubularmember 27 is provided with an internal sleeve 30 constitutis `mounted on a valve stemv 32ztliat has -a notch v33 near its lower end inwhich seats l'a pin 34 secured to theiarms' 25 `ofi said float' F u'eloil or other liquid entering the top of Vthe upper` housing 1y passes through vthe 5 27 passes the valve31- into the lower housing Y 21,/whence it io'ws'to the'burner orv other del vice.Y As tlielower housing 21 fills up, the float24 rises carrying with it the vvalve 31 and When'theliquid reaches a certain level, the

valve abuts againstits seat 30,. opening again ing a seat for a conical valve 31. Said valve and through'the tubular member when the liquid level dropsand causes the ,f float 21H0 drop. Thus the liquid is 'kept at a p constant-level in the lower housing.

Extending into an .opening` in the .lower housing is av pipe 35that is `connected with ,the vent pipe 36 of themain supply tank, thereby preventing any overflow incase the valve 31 should stick.

The position of the valve 31 minimizes the risk 'of the valve or its seat becoming clogged with 'foreign mattei' and vfailing to seat prop-Y erly. By closing thev shut-off valve, thc cap 10 may be removed and the interior of the housing 1 inspected or the strainer 5 removed without any liquidfbeing spilled. Thevarious parts are made of materials that are not affected by the liquidbeing fed. Inthe case ofy oil foruse in oil burners the valve 31, valve seat 30 and strainer 5 may bemade of Monel` metal and other parts in contactwith the liquid'may be'inade of brass or bronze so that danger of corrosion is ininimized.` Obviously numerous changes might be made with out departing"fromy the invention and .I do; not wish to be limited to the precise construction shown.

What I claim is:

ico

upper housing having an inlet opening con nected to a supply ofliquid, said upper housing having an openingv in the top, a cap for said opening, a clamp bar having a curved portion engaging said cap to hold it in lace, a strainer in said housing through whidhthe liquid passes, a lower housing'secured to said upper housing` and having an outlet opening between said housings, a valve seat 'in said opening, a float in said lower housing and a valve for said valve seat mounted to risel and fall with said float. v A

2. Aliquid feeding device comprising an upper housing having an inlet opening connected to a supply of liquid, said upper hous- `ing having an annular ledge in its top, a gasket on "iid ledge, a cap having an annular rib on its under side resting on said gasket, a clamp bar secured to said housing and having a. convexly curved portion engaging the top of said cap, a strainer in said housing through which the liquid passes, a lower housing secured tol said upperhousing and hav- Y ing an outlet opening, an opening between said housings, a. valve seatin said opening, a float in said lower housing and a valve for said valve seat mounted to rise and fall with said float. j y

3.
